Swing Drill One

A good drill to begin modifying a swing is to use a club that is slightly weighted.  The extra weight will strengthen the muscles used during a swing and train them to remember the motion of the swing.  This drill by itself will not give a perfect swing but will greatly assist in the mechanics.  Using this with other drills will help improve the swing.

Swing Drill Two

Lie a 2x4 on the ground.  Swing the golf club trying to pass the ground close to the wood without hitting it.  This will teach the golfer to come straight thru with the swing. 

Hitting the beginning of the wood will result in a swing that will produce a slice.  

Hitting the end of the wood will result in drawing the ball.
